BMW performance upgrades, chips, turbo kits and custom tuning.

We have finished the tuning for our BMW 535 stage 1 turbo system for the e34 Chassis. It is safe to say that it will put down 290 wheel horsepower and 270 wheel torque measured on a Mustang 1100SE chassis dynamometer a very conservative reading dyno compared to a DynoJet which is what many companies use to publish power figures.

This power figure comes from an engine that is holding good compression, and is running tight. The engine had 300,000 KM's so by all means, it has seen its fair share of wear. Typically these engines make more torque than power, and with an electronic boost control unit, one would be able to make more torque than 270 Ft.Lbs However, the kit comes with a manual boost controller and runs a safe 8/9 PSI.

With a completely tuned chip, this kit is completely bolt on with no headaches. Tuned out of the box, the kit will provide you with the best drivability. The Miller MS1 basic turbo kit is one of the best systems available for your car. With a lifetime guarantee on many of its components it is hard to compete with the value added of this system.

The following dyno graph shows the smoothed and unsmoothed power out put, as well as a before and after of the same car. Originally, the car was equipped with our MAF system.
